Sounds like you're ready to read a book that changed my business almost overnight.
There are 3 different functions to every sign business: 1) the technician (the guy or gal who "does the work") 2) the manager (the guy or gal who "makes sure the work gets done,") and 3) the entrepreneur (the guy or gal who "was crazy enough to start the business.")
Most sign companies are owned by the guy or gal who was an entrepreneur. But after a certain amount of time (1 year, 2 years, 4 years, or maybe even 20 years,) the entrepreneur was long gone and replaced by the technician who finally starts getting seriously burned-out. And if the original entrepreneur has management skills, they may build a team and successfully grow the enterprise.
But in most cases, the "sign guy" or "sign girl" keeps "doing it, doing it, doing it," and finally reaches bitterness and burn-out. Most people quit. Some are smart enough to sell, and a very, very, few "build it as a business."
Anyway, back to the book that changed my business overnight (I've started, built, and sold 9 companies which most are still in business today- largely or most entirely due to this one single book).
It's called The E-Myth Revisited (originally called The E-Myth) by Michael Gerber. It teaches why almost all business fail (some fast, some slow) and what you can do about it to actually enjoy owning a real company that makes money for you, verses sucking your life away.
I know there are so many "how to" books on the market, but if you're really interested in changing your outlook and strategy towards your sign company, PLEASE at least pick-up a copy and check it out. You can usually buy the book on ebay or Amazon for dollars. Trust me (I have nothing to gain from this), if you read this and implement even a few of the ideas, your life will change very very quickly.
Good luck,
Aloha,
